A remake? Really? Seems pretty original to me!
I would've been far more impressed with this if you had come up with the concept of NINJA GOLF by yourselves. The two terms are practically on opposite poles of each other, golf of being a Scottish game of concentration and serenity, and ninja being a badass Japanese assassin.
The game was actually a little on the repetative side; it would've been a bit more interesting if (1) the fighting was a bit more involved, and (2) if bunkers, rough, water hazards, and woods actually did something to impair how far you hit your next shot. Instead, they merely determine what manner of enemies you will face. If this is because of how the original is, that's fine, but I really would've prefered something a bit more involved.
To those of you who intend to play this game, it's not that hard a game, though the hit detection is a little off. Hazards on the golf course have no effect on your ball, so go ahead and shoot straight for the green. Where the ball lands merely determines what manner of terrain you will have to deal with, as well as the enemies associated with that terrain (whatever's between you and the ball.)
And to the authors, I would be most interested in seeing you guys expand on this theme! This is as close to a contact sport as I have ever seen golf!
